Question

each beaker shown below contains an amphibian egg collected from one of four different locations. which of these beakers contains an egg that would shrink? a 1 b 2 c 3 d 4

Explanation:

Step1: Understand osmosis principle

Water moves from an area of high water - concentration to an area of low water - concentration. An egg will shrink when water moves out of it, which occurs when the water - concentration outside the egg is lower than inside the egg.

Step2: Analyze each beaker

• In beaker 1: Water - concentration outside (93%) is higher than inside (93%), no net water movement.
• In beaker 2: Water - concentration outside (91%) is higher than inside (80%), water will move into the egg.
• In beaker 3: Water - concentration outside (92%) is lower than inside (99%), water will move out of the egg, causing it to shrink.
• In beaker 4: Water - concentration outside (85%) is higher than inside (90%), water will move into the egg.

Answer:

C. 3
